Electric shaver cutter of improved efficacy |
摘要 |
The efficacy of an electric shaver cutter of the vibratory type is improved by providing a region proximate but not at the cutting edge which differs in thickness from the adjacent portions of the cutter. The difference in thickness results in changes in the vibratory amplitude and frequency of the cutter.
